IPC: B25J9/10
Filed: 1990-09-25
Abstract: PURPOSE:To perform automatic blow-off with respect to the refractory-material blow-off region by teaching at least three operational points to the blow-off robot when setting a refractory-material blow-off region, thereby determining the blow-off robot operation region, and thereafter selectively determining the blow-off robot operation pattern within this blow-off robot operation region.

Title: Packet transmitting system
Inventor: TAKAHASHI TOSHIYUKI
Filed: 1985-11-15
Abstract: PURPOSE:To lighten a load imposed upon memory management and to efficiently perform preferential transmission of packets, by storing packets in the memories of repeating lines other than those, whose memories contain waiting packets, the numbers of which exceed set values set to each preferential transmission level, when the numbers of packets waiting in the memories of those, repeating lines exceed the set values. CONSTITUTION:Inputted packets are received by an input means 1 and sent to a discriminating means 2. The discriminating means 2 discriminates the preferential transmission levels of the packets by referring to the header information of packet, etc., and sends the discriminated results to a repeating line determining means 3. A discriminating means 12 outputs the state of numbers of packets currently stored in memories to the repeating line determining means 3 in accordance with the numbers of packets stored in the memories 5 and 6 of each repeating line and the set value of a setting means 10. When the packet which is discriminated as one whose preferential transmission level is high by the discriminating means 2 is inputted and a newly set value exceeds the current packet number, the repeating line determining means 3 selects the next repeating line.

Title: Bar code handy terminal and charging device
Inventor: INAGAKI AKIHIRO
IPC: G06K7/01
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To prevent a secondary coil and a primary coil from making a grip part and a charging device large-sized respectively with respect to a bar code handy terminal using electromagnetic coupling. SOLUTION: Since end faces 22a and 22b of a secondary coil 22 are arranged so as to face a storage battery storage part 18, the secondary coil 22 overlaps the storage battery storage part 18 in the shorter axial direction, and it is unnecessary to make a grip part 8 thicker even in the part of the storage battery storage part 18. Since a charging device 4 is arranged in accordance with arrangement of the secondary coil 22 of a bar code handy terminal 2 so that a primary coil 36 is on the inside of a side face of a slot part 32 and an end face 36a of the primary coil 36 is approximately parallel with the side face of the slot part 32, it is unnecessary that the primary coil 36 is arranged under a bottom part 32a of the slot part 32 as conventional, and thus, the height of the charging device is suppressed and it is not made large-sized.

Title: Heat storage tank
Inventor: OBARA SHUNPEI
IPC: F24F5/00
Filed: 1987-10-09
Abstract: PURPOSE:To provide a heat storage tank which yields a high heat storage efficiency by employing a length of a flexible tube that opens in the upper part of a high- temperature side water tank and suspending the open end of it at a certain distance from the water surface in the water body by means of a float that floats on the water surface in the water tank so as to stabilize the water flow. CONSTITUTION:A flexible tube 8 has at its open end a ring 10 which is suspended from a float 11 by a suspension rope 12. As cold water supplied through a pipe 16 is fed to the bottom of a water tank 2a, it replaces lukewarm water. When the boundary between cold water and lukewarm water rises as high as the level of the open end ring 10 of the tube 6, the cold water flows into the lower layer in a water tank 2b. The replacement of lukewarm water by cold water takes place between the upper and lower layers in a water tank and between the water tanks, and the water temperature becomes highest at the upper layer of the final water tank 2h. The distance (d) of the open end of the tubes 17, 6 from the water surface is constant regardless of the water level. Therefore, the velocity (v) of water flowing out never exceeds a predetermined value. Thus, the water flow can steadily be controlled to improve the heat storage efficiency.

Title: Duplication of hologram
Inventor: EGUCHI SHIN
IPC: G03H1/18
Filed: 1991-10-03
Abstract: PURPOSE:To allow an easy duplication of hologram patterns without entailing the failure of a work even if the grooves of the desired hologram patterns are deep or fine in pitch. CONSTITUTION:A mask 26 is disposed between the work 24 and a UV lamp at the time of irradiating the work 24 with UV rays. The mask 26 is so formed that its UV transmittance decreases continuously from the inside of the regions formed with the desired hologram patterns to the boundary of the region. The adhesion between a stamper 21 and the work 24 decreases when the irradiation quantity of UV rays decreases in the region A having the hologram patterns and, therefore, the adhesion decreases continuously from the inside of the region formed with the desired hologram patterns to the boundary of this region. Since the level difference of the adhesion at this boundary decreases, the work 24 can be peeled from the stamper 21 while the excess stress concn. is averted.
